Abstract [en]

The decision about which constructing method that will be used must be taken in an early stage of planning. There are many different methods in order to construct one and a same part of a building. In this report, we describe two construction methods for flooring elements. The choice of construction method is a current question on Åhlin & Ekeroth AB and the company is on an expansive advance. In order to make their methods more efficient the task of investigating this matter has been given to us. Our main goal is to decide whether it is more appropriate to build a flooring element on-the-spot or with prefabricated flooring- cassettes.

We had the possibility to observe an ongoing project in a district called Lambohov and decided to make an investigation of which type of wooden beam is most suitable for small buildings. We mention two kinds of beams in this report. One of them is called the masonitebeam and the other one is an ordinary beam.

In order to give the report a larger genuine value we implemented interviews of persons with appreciable experience within the construction industry. Their opinions and knowledge has been to a big assistance in our researching. It has also emerged a lot of exciting facts due to our strategy to give the persons plenty of room during the interviews.

In order to get closer the truth about which construction method that is most appropriate for small houses we also performed some economical calculations. Despite of everything it is the economic factor that often decides which constructing method that will be used. We know that the prefabricated flooring- element has a higher price and installation cost but is constructed much faster. The question of which constructing method is the economic most favourable in contrast to the total cost remains to be answered and we would recommend a wider research in this matter.

We hope that the report will be a basis in the future for Åhlin & Ekeroth AB when the company carries out similar projects as the ones on Kv Isglassen and Kv Isskulpturen.
